5. TECHNICAL DESCRIPTION
The cookers of La Nordica are suitable to cook on the grill and on the oven and to heat living spaces for some periods or to support an
insufficient centralized heating system. They are ideal for holiday apartments and weekend houses or as an auxiliary heating system during
the whole year. As fuel, wood logs is used. The appliance works as an intermittent operating appliance.
The cooker is made of galvanized and enamelled steel sheets and enamelled cast iron (doors, front side, plate).The hearth is totally
sheathed with single cast iron sheets. Inside there is a thick flat grate.
Under the oven door there is an extractable food warmer drawer, with the related closing door: never introduce flammable objects or
materials
(Picture 6 at page 42
The heating of the environment is made by irradiation: through the external hot surfaces of the stove, the heat is radiated into the
environment.
The cooker is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
PRIMARY AIR CONTROL (PRE-ADJUSTED)
SECONDARY AIR CONTROL (PRE-ADJUSTED)
A – SMOKES control

(Conversion of the cooker function to the cooker, bake oven and heating function).
The smokes control, in the style of a chromed pull push lever, can be found on the top right corner of the front side of the cooker, between
the protection bar and the oven door. This control has two settings:
HOB COOKING: when the bar is pushed to the back of the cooker, the combustion gases flow around the oven and directly into the flue
and up to the chimney. OVEN COOKING: when the control bar is pulled out, the combustion gases flow around the oven, heating it.
To ignite the flame follow the instructions below (see Cap. IGNITION) :
•
Bring the flue gas control to the cooker position (any butterfly valve placed on the flue gas exhaust pipe must also be opened).
•
After having started the fire with small pieces of wood and waited until it is well lit.
•
Bring the flue gas control to the oven position.
•
Close any butterfly valve placed on the flue gas exhaust pipe must also be opened.
The control regulation during the ignition phase is the following :
ROMANTICA
The control regulation necessary in order to obtain nominal calorific output is the following (see Cap. TECHNICAL DATA):
ROMANTICA
6. FLUE
Essential requirements for correct appliance operation:
•
the internal section must preferably be circular;
•
the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to heat, combustion
products and any condensation;
•
there must be no narrowing and vertical passages with deviations must not be greater than 45°;
•
if already used, it must be clean;
•
the technical data from the instruction manual must be respected;
If the flues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm.
For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.
A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.
The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel, rough
and porous internal surfaces.
The minimum section must be 4 dm
dm
(for example 25x25 cm) for appliances with a diameter of more than 200 mm.
2
The draught created by your flue must be sufficient but not excessive.
A section of the flue which is too large can present a volume which is too large to heat and therefore cause operating difficulties for the
appliance; to avoid this, it is necessary to intubate the appliance for its entire height. A section which is too small causes a reduction in
draught.
The flue must be at a suitably distance from flammable or combustible material using suitable insulation or an air space.
It is FORBIDDEN to pass system piping or air ducts inside the flue. It is also forbidden to create moveable or fixed openings on the flue
itself, for the connection of further different appliances (See chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE).
